Steering deadzone

The thumbsticks, however, clearly have a deadzone of 2.4mm and an acceleration as soon as the F310 detects movement. As a result, characters or vehicles in a game can not be controlled as precisely.

Even the next model up sucks too.

Because of its inferior vibration function, the dead zone in the thumbsticks and the unwieldy triggers, we find ourselves unable to recommend the Logitech F710.

You need to drop more than $30 if you want good thumbsticks.

The [Microsoft Xbox 360 Controller] thumbsticks do not have a dead zone and operate in a very precise manner, offering you a great degree of precision when controlling a character or a vehicle.

Even with a 360 controller you still have to 'click' for fine adjustments - that's the down side of not having a dead zone. There are always tell tail sounds of someone playing a racing game with a 360 controller - the stick snapping back to zero every 1/8th of a second... which is where the intrinsic problem comes into play:

We only noticed one flaw: the thumbsticks do not always properly reset to the central position, but sometimes keep transmitting the tiniest of movements.

Just be sure that you're not buying a MS knockoff. I love Logitech, but they should stick to making mice.
